Definitions

  • This invention relates to a photographic element for color diffusion transfer photography wherein a ballasted 2,5-di-sulfonamidophenol compound is used to scavenge oxidized electron transfer agents.
  • U.S. Patent 4,076,529 describes various color image transfer elements which employ nondiffusible, redox-dye-releasing compounds which are alkali-cleavable upon oxidation to release a diffusible color-providing moiety.
  • An electron transfer agent (ETA) is oxidized as a function of development. The ETA ox then cross-oxidizes the dye-releasing compound. Interlayers containing scavenging compounds, such as 2,5-di-sec-dodecylhydroquinone, are usually employed in these elements. Such compounds prevent the ETA which is oxidized as a function of development of one emulsion layer from migrating to adjacent imaging layers where it would cause the "wrong" dye to be released.
  • a photographic element in accordance with this invention to be processed with an electron transfer agent, comprises a support having thereon at least one photosensitive silver halide emulsion layer having associated therewith a dye image-providing material which is a ballasted redox-dye-releasing compound and this element contains also a scavenger having the following formula: wherein each R represents a substituted or unsubstituted alkyl or aryl group, with the proviso that at least one R is of such molecular size and configuration as to render the compound nondiffusible in the photographic element during development in an alkaline processing composition, said scavenger being capable of being oxidized by reacting with an oxidized electron transfer agent to regenerate said electron transfer agent, said scavenger being also separate and distinct from said dye image-providing material.
  • each R can independently represent an alkyl group, including a substituted alkyl group, such as those having from 1 to 40 carbon atoms, e.g., methyl, ethyl, isopropyl, butyl, pentyl, hydroxyethyl, decyl, dodecyl, etc; or an aryl group, including a substituted aryl group, such as those having from 6 to 40 carbon atoms, e.g., phenyl, p-methoxyphenyl, p-sulfamoylphenyl, p-N-dodecylsulfamylphenyl, p-dodecylphenyl, 2,4-ti-t-pentylphenyl, 2-methoxy-4-octadecylphenyl, 4-phenoxyphenyl, o-dodecyloxy-p-tolyl, etc; so long as at least one R
  • each R can independently represent a phenyl group or a phenyl group substituted with additional substituents, such as substituted or unsubstituted alkyl, aryl, acyl, acylamino, alkoxy, aryloxy, sulfonamido, carbamoyl, sulfamoyl, sulfonyl and the like.
  • additional substituents such as substituted or unsubstituted alkyl, aryl, acyl, acylamino, alkoxy, aryloxy, sulfonamido, carbamoyl, sulfamoyl, sulfonyl and the like.
  • R is phenyl, C 6 H 4 OC 16 H 33 or C 6 H 4 OC 12 H 25 .
  • US-A-2,569,906 describes a silver halide material containing a 2,5-disulfonamidophenol.
  • this compound is a color-former producing an azine dye through the reaction with an oxidized color developing agent of the aromatic primary amine type followed by a ring closure.
  • the scavenger compound is located in the photographic element in an interlayer between the various emulsion layers.
  • interlayers typically comprise the compound, gelatin, a coupler solvent and other usual addenda.
  • the compound can be employed in any amount which is effective for the intended purpose. Good results have been obtained when the compound is employed in a coverage of from about 200 to 2,000 mg/m 2 .
  • the compound can also be located in other positions in the photographic element, such as in a silver halide emulsion layer or in the dye image-providing material layer. In these latter two locations, the compound could scavenge a portion of the oxidized developing agent before it can react with the dye image-providing material and therefore act as a competer for oxidized developer.
  • competers are useful in diffusion transfer systems when development takes place at higher than optimum temperatures. For example, at high temperatures, such as 32 to 35°C, there can be excessive development, which causes more oxidized developing agent to be generated and more dye to be released.
  • the presence of a competer will help to alleviate the problem somewhat by scavenging a portion of the oxidized developing agent to reduce the amount of dye released.
  • the compound when used as a competer, can be employed in any amount which is effective for the intended purpose. Good results have usually been obtained when the compound is employed in a coverage of from about 5 to 500 mg/m 2 .
  • the dye image-providing material useful in this invention can be positive- or negative-working, and can be initially mobile or immobile in the photographic element during processing with an alkaline composition.
  • initially mobile, positive-working dye image-providing materials useful in this invention are described in U.S. Patents 2,983,606; 3,536,739; 3,705,184; 3,482,972; 2,756,142; 3,880,658 and 3,854,985.
  • the nondiffusible RDR's are ballasted p-sulfonamidonaphthol compounds, each of which has a color-providing moiety attached thereto through a sulfonamido group which is alkali-cleavable upon oxidation.
  • a process for producing a photographic image in color according to this invention comprises:
  • a process for producing a photographic image in color according to this invention using a preferred element as described above wherein the nondiffusible RDR is a ballasted compound having a color-providing moiety attached thereto through a sulfonamido group which is alkali-cleavable upon oxidation comprises:
  • an imagewise distribution of dye in addition to developed silver.
  • a color image comprising residual nondiffusible compound may be obtained in these elements if the residual silver and silver halide are removed in any conventional manner well known to those skilled in the photographic art, such as a bleach bath followed by a fix bath, a bleach-fix bath, etc.
  • the imagewise distribution of dye may also diffuse out of these elements into these baths, if desired, rather than to an image-receiving element.
  • the photographic element in the above-described processes can be treated with an alkaline processing composition to effect or initiate development in any manner.
  • a preferred method for applying processing composition is by use of a rupturable container or pod which contains the composition.
  • the processing composition employed in this invention contains the developing agent for development, although the composition could also be solely an alkaline solution where the developer is incorporated in the photographic element, the image-receiving element or the process sheet, in which case the alkaline solution serves to activate the incorporated developer.
  • a photographic element in accordance with this invention includes an assemblage which is adapted to be processed by an alkaline processing composition, and comprises:
  • the processing composition may be inserted into the film unit, such as by interjecting processing solution with communicating members similar to hypodermic syringes which are attached either to a camera or camera cartridge.
  • the processing composition may also be applied by means of a swab or by dipping in a bath, if so desired.
  • the assemblage itself contains the alkaline processing composition and means containing same for discharage within the film unit, such as a rupturable container which is adapted to be positioned during processing of the film unit so that a compressive force applied to the container by pressure-applying members, such as would be found in a camera designed for in-camera processing, will effect a discharge of the container's contents within the film unit.
  • a rupturable container which is adapted to be positioned during processing of the film unit so that a compressive force applied to the container by pressure-applying members, such as would be found in a camera designed for in-camera processing, will effect a discharge of the container's contents within the film unit.
  • the dye image-receiving layer in the above-described assemblage can be located on a separate support adapted to be superposed on the photographic element after exposure thereof.
  • image-receiving elements are generally disclosed, for example, in U.S. Patent 3,362,819.
  • the means for discharging the processing composition is a rupturable container, it is usually positioned in relation to the photographic element and the image-receiving element so that a compressive force applied to the container by pressure-applying members, such as would be found in a typical camera used for in-camera processing, will effect a discharge of the container's contents between the image-receiving element and the outermost layer of the photographic element.
  • the dye image-receiving element is separated from the photographic element.
  • the dye image-receiving layer in the above-described film unit can also be located integral with the photographic element between the support and the lowermost photosensitive silver halide emulsion layer.
  • Useful formats for integral receiver-negative photographic elements are disclosed in Belgian Patents 757,959 and 757,960.
  • each silver halide emulsion layer of the film assembly will have associated therewith a dye image-providing material which possesses a predominant spectral absorption within the region of the visible spectrum to which said silver halide emulsion is sensitive, i.e., the blue-sensitive silver halide emulsion layer will have a yellow dye image-providing material associated therewith, the green-sensitive silver halide emulsion layer will have a magenta dye image-providing material associated therewith, and the red-sensitive silver halide emulsion layer will have a cyan dye image-providing material associated therewith.
  • the dye image-providing material associated with each silver halide emulssion layer may be contained either in the silver halide emulsion layer itself or in a layer contiguous to the silver halide emulsion layer, i.e., the dye image-providing material may be coated in a separate layer underneath the silver halide emulsion layer with respect to the exposure direction.
  • the concentration of the dye image-providing material that is employed in the present invention may be varied over a wide range, depending upon the particular compound employed and the results desired.
  • the dye image-providing material may be coated in a layer at a concentration of 0.1 to 3 g/m 2 .
  • the dye image-providing material may be dispersed in a hydrophilic film-forming natural material or synthetic polymer, such as gelatin, polyvinyl alcohol, etc, which is adapted to be permeated by aqueous alkaline processing composition.
  • a variety of silver halide developing agents can be employed in this invention.
  • developers or ETA compounds which can be employed include hydroquinone compounds, aminophenol compounds, catechol compounds and phenylenediamine compounds.
  • the ETA is a 3-pyrazolidinone compound.
  • a combination of different ETA's, such as those disclosed in U.S. Patent 3,039,869, can also be employed.
  • Such developing agents can be employed in the liquid processing composition or may be contained, at least in part, in any layer or layers of the photographic element to be activated by the alkaline processing composition, such as in the silver halide emulsion layers, the dye image-providing material layers, interlayers, image-receiving layer, etc.
  • either conventional negative-working or direct-positive silver halide emulsions may be employed.
  • the silver halide emulsion employed is a direct-positive silver halide emulsion, such as an internal-image emulsion designed for use in the integral image reversal process, or a fogged, direct-positive emulsion such as a solarizing emulsion, which is developable in unexposed areas, a positive image can be obtained on the dye image-receiving layer by using ballasted, redox, dye-releasers.
  • the various silver halide emulsion layers employed in this invention can be disposed in the usual order, i.e., the blue-sensitive silver halide emulsion layer first with respect to the exposure side, followed by the green-sensitive and red-sensitive silver halide emulsion layers.
  • any material can be employed as the image-receiving layer in this invention as long as the desired function of mordanting or otherwise fixing the dye images is obtained.
  • the particular material chosen will depend upon the dye to be mordanted. Suitable materials are disclosed on pages 80 through 82 of the November 1976 edition of Research Disclosure.
  • pH-lowering material in the film units of this invention will usually increase the stability of the transferred image.
  • the pH-lowering material will effect a reduction in the pH of the image layer from about 13 or 14 to at least 11 and preferably 5 to 8 within a short time after imbibition.
  • Suitable materials and their functions are disclosed on pages 22 and 23 of the July 1974 edition of Research Disclosure, and pages 35 through 37 of the July 1975 edtion of Research Disclosure.
  • a timing or inert spacer layer can be employed in the practice of this invention over the pH-lowering layer which "times" or controls the pH reduction as a function of the rate at which the alkaline composition diffuses through the inert spacer layer. Examples of such timing layers and their functions are disclosed in the Research Disclosure articles mentioned in the paragraph above concerning pH-lowering layers.
  • the alkaline processing composition employed in this invention is the conventional aqueous solution of an alkaline material, e.g., alkali metal hydroxides or carbonates such as sodium hydroxide, sodium carbonate or an amine such as diethylamine, preferably possessing a pH in excess of 11, and preferably containing a developing agent as described previously. Suitable materials and addenda frequently added to such compositions are disclosed on pages 79 and 80 of the November 1976 edition of Research Disclosure.
  • an alkaline material e.g., alkali metal hydroxides or carbonates such as sodium hydroxide, sodium carbonate or an amine such as diethylamine
  • silver halide emulsions useful in this invention are well known to those skilled in the art and are described in Product Licensing Index, Volume 92, December 1971, publication 9232.
  • nondiffusing used herein has the meaning commonly applied to the term in photography and denotes materials that for all practical purposes do not migrate or wander through organic colloid layers, such as gelatin, in the photographic elements of the invention in an alkaline medium and preferably when processed in a medium having a pH of 11 or greater. The same meaning is to be attached to the term “immobile”.
  • diffusible as applied to the materials of this invention has the converse meaning and denotes materials having the property of diffusing effectively through the colloid layers of the photographic elements in an alkaline medium.
  • Mobile has the same meaning as "diffusible”.
  • a Parr bottle was charged with the nitro compound L (5.40 g, 0.010 mole), 2 to 3 g of Pd/C catalyst, 100 ml of THF and shaken under H 2 at an initial pressure of 227 kPa; after 10 minutes, the pressure had dropped to 89 kPa; refilled to 214 kPa; after 15 minutes, it was 172,5 kPa; after 90 minutes, 138 kPa; after shaking overnight, it was 110,5 kPa.
  • the catalyst was removed by filtration, and the clear, faintly pink filtrate was treated with NaHCO 3 (2.0 g, 0.024 mole) and the acid chloride N (3.1 g, 0.010 mole). After 1 hour, gas evolution had stopped.
  • One sample of each of the above-prepared photosensitive elements was exposed through a graduated-density test object.
  • the exposed samples were then processed at 21 °C by rupturing a pod containing a viscous processing composition between the photosensitive element and a transparent cover sheet, as described below.
  • the processing composition was as follows:
  • the cover sheet consisted of a transparent poly(ethylene terephthalate) film support having coated thereon:
  • the oxidized developing agent (4-hydroxymethyl-4-methyl-1-phenyl-3-pyrazolidone) migrated to the yellow RDR layer, reacted with the RDR to release a diffusible yellow dye, which then caused the relative high blue density values.
  • the blue densities were significantly reduced relative to the control elements, thus indicating that they were highly effective in scavenging the oxidized developing agent, both in the fresh samples and after incubation.
